Tl efrontot theohamben?) is In the embodiment "illustrated"the drier also pro-Yidec'l with doors -17 hinged at 13 Lil andv provided with. a latch 19, whereby acthe macaroni about in the chambers as the cess is had to the interior of chamber 3 for opening or closing the doors 12 and for other purposes.

As illustrated in Figs. 2 and a the drawers consist. of suitable side walls 22 and have a screen bottom 23 to permit tree circulation of the air through the macaroni therein. The walls 22 are rabbeted at 24 to provide an easy means for fastening the screens 23 in the drawers. Handles 25 are provided. for manipulating the drawers.

In the operation of the drier as illustrated in Fig. 1 the macaroni is placed in the drawers 8, and the drawers slide into chambers 1, the doors 7 at the front and back of the chan'iber are opened and the fan 13 is started to draw the air through the openings 7, down through the macaroni in drawers 8, through compartment 10, opening 11 and out through the door 16 in the chamber 8 as indicated by the arrows.

During the drying of the macaroni in the chamber 1 the macaroni being made in the l'actory can be placed in the chamber 2. The circulation of the air through chamber 2 during this period is prevented by the closed doors 12 and 7.

lVhen the macaroni in the chamber 1 is dried sufiiciently,the "tan is stopped, and the doors 7 and 12 of the chamber 1 and door 16 of chamber 3 are closed, whereupon the dried macaroni can be removed and the drawers refilled with undried macaroni.

During the refilling of the drawers in the chamber 1, the macaroni placed in the chamher 2 may be dried by opening the doors 7, 12 and 15, and starting the fan in reverse direction to draw the air down through the chamber 2 and out through the opening controlled by door 15.

The size of the drier and the rate of drying may be coordinated with the output of the factory so that din-ing the time required to dry the macaroni in one chamber, the other chamber may be unpacked and refilled, the chambers being adapted to hold all the macaroni produced in the meantime so that there is always one chamber in the process of beingdried and another in the process of being unpacked and refilled.

By this arrangement the output of the factory can be made continuous as it is never necessary to stop production and wait until the drying is finished in order to have a place for the disposal of the formed macaroni.

By the use of this drier it has been found that the macaroni may be safely dried in as little a time as one hour without causing cracks therein, that the drying'is much more uniform than in the pressure driers where the part ofthe macaroni near the fan is subjected to a strong blast of air and that remote from the fan to a weakened air blast, and that the suction current does not blow pressure driers sometimes do.

Vhile the invention has been described with reference to two drying chambers it is obvious that the principles of the invention may be applied to a drier with a plurality of chambers and that various other modifications and changes may be made without departing from the spirit of the invention as defined in the claims, which are intended to claim the invention as broadly as the state of the prior art will permit.

What we claim is:

1. In a drier for macaroni or the like the combination of a plurality of drying chambers, an intermediate chamber communicating therewith, suction means in the intermediate chamber, and doors between the drying chambers and the intermediate chamber to permit the suction means to circulate the drying medium through one chamber while circulation through the other chamber is prevented.

2. In a drier for macaroni, or the like, the combination of a pair of drying chambers, and an intermediate chamber having openings in. the drying chambers, a fan in the intermediate chamber, means to close said openings to permit the fan to circulate the drying medium through one chamber and exhaust it through the intermediate chamber and means to prevent the circulation of the drying medium through the other chamber, said means and said fan being reversible to cause the medium to circulate through either chamber.

3. In a drier for macaroni or the like, the combination of a pair of drying chambers, a fan chamber connecting the drying chambers and communicating therewith a reversible fan in said chamber and means to control the communication so that air may be circulated through either chamber while circulation through the other chan'iber is prevented.

4. In a drier for macaroni or the like, a pair of drying chambers having openings at one extremity thereof, an intermediate fan chamber communicating with the drying chambers near the other extremity thereof, and means to draw air from the openings through either drying chamber and discharge it from the intermediate chamber.

5. In a drier for macaroni or the like, the combination of a pair of drying chambers having openings therein, an intermediate chamber, communicating with each drying chamber, means to stop communication between the intermediatechamber and either drying chamber, a fan in the intermediate chamber and a door opening to the atmosphere at each side of the fan, whereby air may be drawn through either of the drying chambers and discharged through the intermediate chamber, while circulation of air IGN- V vented.
